Hi Everyone,About 10 years ago I felt pain between my left waist and my lower-left abdomen, each time I had sex with my girlfriend. I had colonoscopy but everything was normal, so my Dr said it was probably just spasm. Later the pain went awayAbout 4-5 years ago, I had abdominal pain. It is about 1 inch below and 2 inch left of my navel. CT was normal, my Dr said I may be too stressful and I felt a relief and then the pain went away.About 5 month ago, I had a big quarrel with my family and right after the fight I felt pain at the point about 1 inch below and 2 inch left of my navel. Since then the pain has been on and off. It normally lasts about 2 weeks for everyday. Then after that I felt very normal, and I tended to stay up late and became not as careful as before. As the result the pain came back after a week. The pain is very annoying and I can locate the position, but it is not acute.. It comes and goes everyday. Sometimes the pain is gone but I feel tight, sour or cold at my left waist or a little back of my left waist. It leads me to want some massage using my hands, even though it does not help much. I am sure the sensations at waist are together with my abdominal pain. BTW, if I get distracted (for example installing a range hood in my kitchen last weekend, i tend to forget about the pain or the pain tends to disappear for awhile)I do not have diarrhea, constipation, gas, or bloatedness. No blood in stool. No urine problem.Can anyone tell me if this is IBS? Does IBS always come with diarrhea, constipation, gas, or bloatedness?Sorry for being wordy.. I am just trying to give as many details as possible to help you to help me..Thank you very much!
